Still not clear.  They are defined in cl-lib only when
PLACE is a var name?  They don't cause other components
to be loaded only when PLACE is a var name?

It's not clear to me whether you've fixed the doc or are
just trying to explain it to me.  If the latter then this
is, I guess, a "won't fix".  (It needs to be fixed.)

Dunno what that means.  Does it mean that `Lists as Sets'
has been updated to cover the keyword args, including
:test?
